Embodiment Construction
[0029] exist figure 1 and 2 In , an embodiment of a leaf spring 1 of a leaf spring assembly according to the invention is shown in side and perspective views. In this case, the leaf spring 1 made of fiber composite material has a length L and a height H and a width T at its ends 4 and 5 . In this case, the height H is substantially perpendicular to the width T, so that the height H and the width T define the cross-section of the leaf spring 1 in its longitudinal extent along the length of the ends 4 and 5 . In this case, the cross section is substantially rectangular, wherein the corners are rounded. Due to the uniform cross-section on the longitudinal extent of the ends 4 and 5 of the leaf spring 1, the ends 4 and 5 of the leaf spring 1 may require no material addition or material reduction in order to be used in the leaf spring assembly according to the invention .
[0030] Here, the leaf spring 1 is figure 1 and 2 The central right-hand end 4 has a corrugation 8 , whe...

The invention relates to a leaf spring assembly with a leaf spring made of fiber composite material and a bearing hole holder, wherein the end of the leaf spring is positively received in the bearing hole holder in the longitudinal direction of the leaf spring In the retaining element, wherein the leaf spring has a length and a longitudinal middle surface, wherein the leaf spring has a cross-section along its length perpendicular to the longitudinal middle surface, in which width and height are over the entire length of the ends of the leaf spring is constant, wherein the end of the leaf spring is configured in a corrugated manner, wherein the holding element of the bearing hole holding device has a receptacle having a corrugated shape adapted to the end, wherein the end of the leaf spring There is a bellows, wherein the receptacle of the bearing bore holder is configured for receiving the bellows of the leaf spring. The leaf spring assembly is characterized in that the end of the leaf spring has two bellows, wherein the receptacle of the bearing bore holder is configured for positively fitting reception of the two bellows of the leaf spring.
Description
technical field [0001] The invention relates to a leaf spring assembly with a leaf spring made of fiber composite material and at least one bearing bore holder. Background technique [0002] Conventional leaf springs made of fiber composite material are usually designed uniformly over their entire longitudinal extent, so that they have a consistent fiber volume ratio over their entire longitudinal extent. For the non-positive connection of the leaf spring to the bearing hole holder, it is provided here that mechanical fastening elements, such as clamping sleeves or through-bolts, are provided, which pass both through the corresponding openings of the bearing hole holder and through the opening of the leaf spring. Corresponding openings are provided for non-positive connection of the leaf spring to the bearing bore holder. Such an assembly is described, for example, in EP 007 012 B. In this case, however, when dynamic loads occur when using such leaf spring assemblies, a re...
